CPXXmultiobjgetdiminfo

Description

The routine CPXXmultiobjgetdiminfo accesses integer-valued information about the solution of the specified subproblem during the last multi-objective optimization.

The specified subproblem must have been solved during the last multi-objective optimization, or no information can be retreived for it.

The info values are returned in the variable int pointed to by the argument info_p.

For documentation of the info symbols (possible values of the what argument), see the CPX_MULTIOBJ_... symbols on the page, Multiobjective optimization in the CPLEX Callable Library (C API), in the Callable Library (C API) Reference Manual..

Arguments

env

A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.

lp

A pointer to a CPLEX problem object as returned by CPXXcreateprob/CPXcreateprob.

subprob

An integer value specifying the order number of the multi-objective subproblem for which the information is requested.

info_p

A pointer to an integer variable in which the requested info value is to be stored.

what

A symbolic constant specifying the info value to be retrieved.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.

Example

status = CPXXmultiobjgetdiminfo (env, lp, &priority, CPX_MULTIOBJ_PRIORITY);
